Sorry, Shakerpaging will never work on P99.
Furious disc is not the same as Rampage AA*.
PC's do not proc on Ripos; however, NPCs can, which is why you have to attack VS from behind now.
Edit: Additional discussion of innate procs on PC and NPC in this thread:

Edit2: Corrected Rampage disc to AA, was beyond my time on live. :P
